switch off those lights, in the name of saving energy and combating global warming, and seeing more stars!
It is. The government is trying to create a vibrant city with good night life similar to that in Hong Kong to promote tourism and night entertainment industry. To do this, its master plan calls for lighting up of the night sky. Ironically, Hong Kong is now calling this a waste of energy and trying to cut down!kingkong wrote:i don't understand how stopping spotlights from pointing upwards is economically not viable.
if we, the educated and supposedly enlightened, succumb to the myths that what's good for the environment is necessarily bad for business, or things is so bad nothing can be done now, or global warming is exaggeration, or providing clean air and clean water are the jobs of the less developed; then indeed we are doomed.
for your info, johor is joining singapore soon as they are also building up rapidly. mersing is no longer as dark as it was several years ago and the skyglow is quite irritating now, not to mention another sky glow developing in the opp direction....sigh...madsock wrote:Not that i am promoting light pollution, but having a well lit city will sort of promote that crime rate be low, city is safe, drivers can see the road... etc. Basically good things we are enjoying right now.
Although having the lights point UPWARDS does not make any sense.
but talking about light pollution, as long as there is a lousy street lamp in the vacinity, your stargazing chances are sort of ruined.
sigh.... so we'll go to johor to look at stars....
actually our current use of lights is not efficient. Let's take a street lamp for example. Only 60% of the light shine downwards illuminating the road, but 40% shine upwards for nothing except polluting the sky.madsock wrote:Not that i am promoting light pollution, but having a well lit city will sort of promote that crime rate be low, city is safe, drivers can see the road... etc. Basically good things we are enjoying right now.
